Police in southwestern Germany launched a manhunt on Monday after a teenager entered a vocational school in the town of Esslingen reportedly armed with a gun and later fled without causing any injuries.

The suspect, who did not fire his gun, was only briefly in the Friedrich-Ebert School and later fled on a motorcycle, Reutlingen police (Polizei Reutlingen) said on Twitter.

After receiving calls from students, the police locked down and searched the school, finding nothing suspicious, Xinhua reported.
